[ic] Not working in 4.7.2

[interch]

This works in 4.6.5 but not 4.7.2:

[perl tables=products]
$items = $Tag->item_list({ }, "[item-code];[item-description];[item-field
item_type];S;[item-price noformat];;[item-quantity]|");
chop($items);
$Values->{item_list} = $items;
return();
[/perl]


The item_type field does exist, and I get the same error even if I take
out the [item-field item_type] parameter.  The error in error.log is as
follows:
